Abstract: Background　In recent years，patients with atrial fibrillation and coronary heart disease have attracted more and more attention in clinic.Recent clinical studies mainly focused on the prevention and treatment of stroke and thromboembolic events.Objective　To evaluate the long-term survival rate of elderly patients with ischemic stroke combined with atrial fibrillation and coronary heart disease，and analyze the risk factors which affected the prognosis.Methods　We conducted a retrospective cohort study.A retrospective analysis of 406 patients over 60 years admitted to hospital due to acute ischemic stroke for the first time were enrolled，and 164 patients with atrial fibrillation and coronary heart disease were selected from them as cerebrovascular disease group，164 patients without cerebrovascular disease but with atrial fibrillation and coronary heart disease matched with age，gender and comorbidities were selected from concurrent hospitalized patients in the Department of Cardiology as non-cerebrovascular disease group.The clinical data，including demographic information，types of diseases，types of medications，blood pressure，heart rate，cardiovascular diseases and other diseases of the two groups were collected，laboratory test，echocardiographic parameters，treatment plan.The CHA2DS2-VASc score and CHADS2 score were used to assess the risk of stroke and thromboembolism，and the HAS-BLED score was used to assess the risk of bleeding.The patients were followed up for at least 6 years by telephone，outpatient and inpatient records after discharge，to record the death，readmission and major adverse cardiovascular events（MACE），and to explore the factors that affect his long-term prognosis.Results　Compared with non-cerebrovascular disease group，the proportion of hyperlipidemia and chronic gastrointestinal disease in cerebrovascular disease group was lower.LVEDD，CHA2DS2-VASc score，CHADS2 score，and the HAS-BLED score in cerebrovascular disease group were higher（P<0.05）.In the 164 patients with cerebrovascular disease group，2 cases were lost to follow-up（1.2%），and 80 cases died（49.4%）.They were divided into death group（80 cases） and survival group（82 cases） according to the survival outcome.The death group was older and had lower systolic and diastolic blood pressure than the survival group，and the proportion of hypertension，hyperlipidemia，serum albumin and the use of statins were also lower than the survival group.The resting heart rate and the proportion of old myocardial infarction，the proportion of heart failure，chronic kidney disease，NYHA，D-dimer and NT-proBNP levels in death group were higher than the survival group（P<0.05）.The results of multivariate Cox regression analysis showed that for every 10 years of age increase〔HR=1.63，95%CI（1.05，2.51）〕，history of old myocardial infarction〔HR=2.19，95%CI（1.14，4.22）〕 and D-Dimer ≥148 μg/L〔HR=6.99，95%CI（2.10，23.28）〕 were independent risk factors for long-term mortality in elderly patients with ischemic stroke combined with atrial fibrillation and coronary heart disease，while hypertension〔HR=0.28，95%CI（0.11，0.72）〕 and statins use〔HR=0.38，95%CI（0.19，0.78）〕 were the protective factors for long-term death in these patients.Conclusion　The long-term mortality of patients with atrial fibrillation and coronary heart disease after the first occurrence of cerebrovascular disease is not related to the coexisting cerebrovascular disease，but related to aging，history of old myocardial infarction and D-dimer level.Maintaining an appropriate blood pressure level and using statins may reduce the long-term mortality patients with atrial fibrillation and coronary heart disease.

摘要： 背景　近年来，心房颤动（简称房颤）合并冠心病患者在临床上越来越受到关注，新近的临床研究主要集中于脑卒中和血栓栓塞事件的预防和治疗。目的　评估老年缺血性脑卒中合并房颤及冠心病患者的远期生存率，分析影响预后的危险因素。方法　本研究为回顾性队列研究，回顾性分析2012年1月—2014年10月首次因急性缺血性脑卒中入住北京医院神经内科病房的患者406例，从中选取同时满足房颤和冠心病诊断标准的60岁以上老年患者共计164例作为脑血管病组，并从心内科同期住院患者中选取年龄、性别、共病种类与其相匹配的房颤合并冠心病但无脑血管病患者164例作为非脑血管病组。收集两组患者的临床资料：包含人口统计学信息、疾病种类、用药种类、血压、心率、合并心脏基础疾病及其他疾病、实验室指标、超声心动图结果、治疗方案；分别通过CHA2DS2-VASc评分、CHADS2评分评估患者的脑卒中及血栓栓塞发生风险，应用HAS-BLED评分评估出血风险，并在其出院后通过定期电话随访、门诊及住院志查询等方式随访至少6年，记录其死亡、再住院次数及主要不良心血管事件（MACE）发生情况，探讨影响其远期预后的因素。结果　脑血管病组合并高脂血症比例、慢性胃肠病比例低于非脑血管病组，LVEDD、CHA2DS2-VASc评分、CHADS2评分、HAS-BLED评分高于非脑血管病组（P<0.05）。脑血管病组164例患者失访2例（失访率1.2%），死亡80例（49.4%），根据生存结局分为死亡组（80例）和存活组（82例）。死亡组患者年龄大于存活组，收缩压、舒张压、合并高血压比例、合并高脂血症比例、血清蛋白、使用他汀类药物比例低于存活组，心率和合并陈旧性心肌梗死、心力衰竭、慢性肾病比例及纽约心脏病协会（NYHA）心功能分级、D-二聚体、N末端B型钠尿肽前体（NT-proBNP）高于存活组（P<0.05）。多因素Cox比例风险回归模型分析结果显示，年龄每增加10岁〔HR=1.63，95%CI（1.05，2.51）〕、陈旧性心肌梗死〔HR=2.19，95%CI（1.14，4.22）〕和D-二聚体≥148 μg/L〔HR=6.99，95%CI（2.10，23.28）〕是老年缺血性脑卒中合并房颤及冠心病患者远期死亡的危险因素，高血压〔HR=0.28，95%CI（0.11，0.72）〕和使用他汀类药物〔HR=0.38，95%CI（0.19，0.78）〕是患者远期死亡的保护因素。结论　房颤合并冠心病患者在首次发生脑血管病后，其远期死亡与并存的脑血管病无关，而与增龄、陈旧性心肌梗死病史及D-二聚体水平有关，维持适当高的血压水平和应用他汀类药物可能会降低远期死亡率。
